A video of the confrontation made it to Twitter. Rex -- wearing a Bryce Harper Nationals jersey -- appears to be in the midst of an argument before it gets physical. After what appears to be a shove toward Rex, Rob Ryan intervenes and is seen putting his hands on another man's throat for a brief moment.

Rex Ryan, who was fired by the Bills with one game remaining in 2016, joined ESPN in April to be a part of the Sunday NFL Countdown in September, while also likely to appear on SportsCenter, among other shows.
